It is a metabolic disease associated with low blood calcium levels. The incidence of clinical hypocalcaemia (milk fever) in the field generally ranges from 0-10%, but may exceed 25% of cows calving. Signs: see below. Milk fever is more commonly seen in olde… CAB Direct provides

In research trials conducted on milk fever the incidence has approached 80% of cows calving. At parturition, the requirement for calcium is greatly increased due to initiation of lactation, when In normal calcium regulation, a decrease in plasma calcium levels causes the It has been found that tissue is less responsive to parathyroid hormone prepartum, compared to postpartum. incorporating the leading bibliographic databases CAB Abstracts and Global Health.

Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle but also seen in beef cattle and non-bovine domesticated animals, characterized by reduced blood calcium levels (hypocalcemia). It is one of the most common bovine metabolic disorders resulting from calcium deficiency.
Stage 3: Lateral recumbency, muscle flaccidity, unresponsiveness to stimuli, and loss of consciousness progressing to coma. Hypocalcaemia around calving is a risk factor for many of these diseases and is an indirect risk factor for increased culling.
It occurs following parturition, at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium. Before calcium injection was employed, treatment comprised inflation of the udder using a pneumatic pump.

It is believed that hypocalcemia causing milk fever is due to a lower level of responsiveness of the cow's tissues to circulating parathyroid hormone.The resultant decreased plasma calcium causes hyperexcitability of the Proper dietary management will prevent most cases of milk fever. If the cow is lying 'flat out' then immediate intravenous therapy is required to avoid death.

Cause: Milk fever is the common name used to describe hypocalcemia in cattle.
The clinical signs of milk fever can be divided into three distinct stages: The incidence of clinical hypocalcaemia (milk fever) in the field generally ranges from 0–10%, but may exceed 25% of cows calving. Inflation of the udder worked because the increased pressure created in the udder pushed the calcium in the udder back into the bloodstream of the cow.Intravenous calcium, though indicated in many cases, is potentially fatal through "heart blockade", or transient high calcium levels stopping the heart, so should be administered with care. Oral administration of a dose of a calcium salt in a gel has been advised by some veterinarians.An orally administered bolus containing a much higher concentration of calcium than the injectable solutions can also be given so long as the cow is standing or sitting up.
